Had a quick look at the spec and the Lapp Olflex 190cy looks quite good.

Thanks Gerald. It seems to be readily available (7 local suppliers) and cost is 20 to 30% less than some of the others.

Where in SA do you get your Lapp cabling from Gerald? I am also in ct.

worth the risk?

Non shielded wire is just asking for trouble. Do you want to spend a lot of time tracking down random glitching and problems?

I wouldn't go unshielded for the motors. You will get loss of steps, and twitching in the motors and other random things when running the machine.

Use the extra Money, and get shielded cables from the start... Anything else is not worth the trouble.

U can try with unshield cable, you might get away with it fi you had done you EMI RFI protection well but are you ready for the complication?

alan254 Mon 25 November 2013 05:22

You can add shielding to any wire. I made all my wire from single wires ( stranded wire from a overhead crane I had). I twisted the wires together as needed then added the shielding , looks like the Chinese finger game you can't your fingers out of then added a jacketing that looks like the same over that. have had on trouble at all since my machine has been running.

its okay...but only 10' long....your going to need 20-30' of each run depending on your controller location. Plus, your steppers don't need to be shielded - only your control circuit wiring.

18 gauge is ok (0.82 mm2) only thing is the aluminium shield, I only used stranded shield
also I think there are more than 7 strands in a single wire in mine, and it should be more flexible than this one.
This looks like cables used for alarms etc... not sure how it will handle bending.

paul60 Tue 26 November 2013 17:40

Ok thanks for the information so the stepper motors dont have to be shielded?
i was not sure.
thanks again
paul

If you take some tome to read this thread from beginning, there are some answers to you even on the first page, first 10 posts

Tom Ayres Tue 26 November 2013 17:45

What are you using it for? The listing doesn't show that its rated for flexing though, you may want check on that. After doing a lot of research myself, I found that the more strands per core the more durable and flexible. Price is nice though.

KenC Tue 26 November 2013 21:32

Usually, the strand number is proportional to flexibility of the cable. More strands per core, more flexible.

I also found this on ebay at the moment there is nothing wrong with my stepper motor cables but i been using them for over 5 years with no problem.
but would hate to have a problem and get stuck waiting for cables.
so i am going to order 100 feet to keep.
my machine is a shopbot using a Mach 3 controller that i built with allot of help
from people on this forum.

my stepper motors are not using screened cables.
and as there is no advantage using screened cables
I will stick to unscreened
thanks again
paul

domino11 Thu 28 November 2013 07:35

Just remember guys, that screening keeps noise in and also keeps it out. You need it on both sides of the coin. Keep the noisy signals from extending out to the sensitive control signals and to keep the sensitive control signals shielded from the noise!

Hello, I think I found a good cable cheap and easy to buy,

McMaster-Carr, as great as they are for getting things to you quickly, tend to have slightly higher prices overall. I have some leftover wire from my build, I sent you an e-mail, let me know if you're interested in it.

hevertg Thu 28 November 2013 13:43

yes
